HUMANS OF THE WORLD- I need your help!!

These ADORABLE humans are my grandparents (the second to last photo is my mommy with my grandma) and they are currently in Nigeria in a pretty desperate situation. I am raising money to help bring them to the USA through gofund me (you can find the link here) or my paypal donation page (linked on my tumblr). This is their situation (words from my go fund me page): 

My grandparents are fast approaching 80 years old and have never had proper medical care before two years ago- when they were able to obtain temporary VISAs to visit the United States. They are back in Nigeria now and their situation is desperate! We are raising money towards the legal fees of filing their paperwork, hiring a lawyer and their plane tickets to come to the USA. Only three members (including myself) of my family are in the West, the rest of my family is back in West Africa. My mother partially supports my brother and I while we are pursing out education and supports my grandparents and other members of my family still in West Africa by wiring money. Due to various health issues and random unfortunate situations, my family is already struggling and bringing my grandparents here is very difficult but we cannot leave them the way they are. Right now they are living alone with no one to aid them, they are farmers so they have to work hard to eat and live, their daily chores are way too laborious for young people, let alone someone their age! They have no help or income assistance, they are isolated from the rest of my family and their health is in poor condition. My grandmother can barely walk, frequently has respiratory problems and chronic skin conditions. My grandfather has one eye, in which he is almost completely blind because of a cataract that doctors refuse to risk operating on, he walks with a limp from a severe farm accident (never treated) that happened years ago and he has trouble performing his daily duties. We just want to bring them here so we can be reunited and so that they can live out their later years in peace.Their situation grows more unfavourable as the part of Nigeria in which they are living gets more dangerous because of multiple terrorist attacks and general political uneasiness.

**please please please, if you can’t help personally, I’d really appreciate if you just reblog or spread the word, it would really help get them out of a bad situation, especially as the situation in their part of Nigeria gets more violent**

Sorry for spamming y’all with my personal business, especially as of late.

New Super Black Material Absorbs 99.965% Of Light
 Goths of the world, rejoice. Scientists have produced Vantablack, a product so dark it becomes impossible to make out shapes formed from it.
Surrey Nanosystems, a British nanoelectronics company have used carbon nanotubes 10,000 times thinner than a human hair to absorb 99.965% of visible light, a world record. The tubes are so small photons cannot get inside, but can fit into the small spaces between the tubes, where they are captured.
For comparison, fresh asphalt reflects 4% of the light that falls on it, and after a while this rises to 12%, while coal seldom gets below 0.5%.
"You expect to see the hills and all you can see … it’s like black, like a hole, like there’s nothing there. It just looks so strange," Surrey Nanosystems’ technical director Ben Jensen told The Independent.
The manufacturers grow Vantablack (Vertically Aligned carbon NanoTube Array) on aluminum foil, making it easy to create complex topography that is entirely invisible to the eye. They point out their low-temperature nanotube growth processes give it a significant advantage past super-black materials that require high temperatures to produce, and are therefore incompatible with sensitive electronics.
While there is probably a market for practical jokes, Surrey Nanosystems are talking up the capacity of Vantablack to calibrate astronomical cameras and infrared scanners, which need to be shown the darkest object possible for comparison with tiny points of light. They also hint darkly at military uses, which may benefit from the enormous tensile strength and heat conductivity.
“We are now scaling up production to meet the requirements of our first customers in the defense and space sectors, and have already delivered our first orders,” said Jensen. So far at least Vantablack is far too expensive to be used for clothes or toys but Jensen said, “You would lose all features of a dress. It would just be something black passing through.”
The properties of Vantablack have been described in Optics Express.

Vaquita (Phocoena sinus)

The vaquita is a rare species of porpoise. It is endemic to the northern part of the Gulf of California. Estimates of the number of individuals alive range from 100  to 300. Vaquitas are the smallest and most endangered species of the cetacean.Vaquitas use high-pitched sounds to communicate with one another and for echolocation to navigate through their habitats. They generally seem to feed and swim at a leisurely pace. Vaquitas avoid all boats and are very evasive. They rise to breathe with a slow forward motion and then disappear quickly. This lack of activity at the surface makes them difficult to observe. Vaquitas are usually alone unless they are accompanied by a calf, meaning that they are less social than other dolphin species. Vaquitas are nonselective predators.

Don’t Cry For Me, Arthropoda: Studies Find Signs of Emotion in Spiders
Individual spiders have character and personality, according to a paper published by theProceedings of the Royal Society B. The paper, titled Individual personalities shape task differentiation in a social spider, gives details of a study into role allocation in spider societies.It was previously assumed that individuals in social spider communities contributed homogenously, with all tasks, such as prey capture and colony defence, being performed equally by members.The study focused on Stegodyphus sarasinorum, a permanently social spider occurring in India and some surrounding countries. Led by Lena Grinsted of Aarhus University in Denmark, over 600 spiders were marked and observed, with tests singling out boldness and aggression. Variances in response showed that individuals were suited to particular roles. 
Individuals in the test group were highly related and of approximately the same age: the only variable was apparently their personality. The study suggests that task allocation is the result of character traits in individual spiders; personality does not appear to be shaped by random selection of task perfomance, therefore.Character and personality are often attributed only to humans, higher order mammals, and birds. Now it appears that arthropods also have responses that could be considered emotional.

THANKS FRIEND

^ What’s your paper? I remember reading a study at my college about how spiders with sociable v. aggressive personalities tend to survive better when territories overlap, I might be able to find the researcher or paper for you. On a side note though, how cute are spooters dsdsdsadsasda <3

An infant gorilla that was being illegally offered for sale this week in Cameroon died before it could be rescued by the Last Great Ape Organization (LAGA) and Cameroonian law enforcement officials, although the dealer was arrested.

Thanks! I feel sooo much better than I did four hours ago or so (though I haven’t got my hopes up get). I was hot, jittery, vomiting constantly, dizzy and anxious and because I have insomnia I couldn’t just sleep through it lol and quitting my meds and sleep aids didn’t help
